Answer:

Step-by-step explanation:

$2x+\frac{12}{7}=3x+\frac{5}{4}\\\\2x-3x=\frac{5}{4}-\frac{12}{7}\\\\-x=\frac{5*7}{4*7}-\frac{12*4}{7*4}\\\\-x=\frac{35}{28}-\frac{48}{28}\\\\-x=\frac{35-48}{28}\\\\-x=\frac{-13}{28}\\\\ x=\frac{13}{28}$

frosja888 [35]

Remember you can do anything to an equation as long as you do it to both sides

5c+16.5=13.5+10c
minus 5c both sides
16.5=13.5+5c
minus 13.5 from both sides
3=5c
divide both sides by 5
3/5=c

11Alexandr11 [23.1K]

Answer and step-by-step explanation:

a. 4 litres in 5 minutes (litres per minute)

4 litres per 5 minutes means 4/5 litres per 1 min = 0.8 litres per minutes

b. 12 litres in 45 minutes = 12/3 litres in 45/3 minutes = 4 litres per 15 minutes

60 minutes = 4*15 minutes

4 * 4 = 16 litres per hour

c. 800 kilowatt hours in 2 months

1 year = 12 months = 2*6 months

kilowatt per year = 800 * 6 = 4800 kilowatt per year

timurjin [86]

The distance from the second destination back to Dallas is 918 miles

<h3>Given</h3>

A triangle has points Dallas, destination 1, and destination 2.

The distance from Dallas to destination 1 is 720 miles

The distance from destination 1 and destination 2 is 290 miles

the angle formed between Dallas, destination 1, and destination 2 is 125 degrees.

He moves from destination 1 to Dallas then destination 2

We could use cosine law to find the distance

<h3>What is cosine law?</h3>

The Law of cosines or cosine law means the relation between the length of sides of a triangle with respect to the cosine of its angle. It is also called the cosine rule

$b^{2}=a^2+c^2-2ac*cosB$
